ARTICLE OF ORNAMENT-.ATION AND METHOD FOR PREPARING SAME No Drawing.

This invention relates to the art of ornamentation and deals more specifically with an article and the method ofpr'oducingthe same which may be cut to any predetermined figure and which is adapted for attachment to any knitted, woven or felted surface by means of an adhesive which becomes tacky upon the application of heat. It has been proposed heretofore to provide articles of ornamentation with a backing of gutta-percha so that the article may be placed in position and a heated iron or roller applied to and/or of heavy quality. In accordance with my invention, however, the desired result may be obtained with light colored materials,

and also with materials of a loosely woven texture. r The manner in which I carry out my in- "vcntionw'ill be readily understood from the following description: j

i A sheet of material having the desired color and texture is first covered with a thin coating of talcum powder or powdered rosin. I thin apply a coating of rubber cement of the kind commercially known as raincoat rubber cement, 'and follow this with a second application of talcum powder or powdered rosin, and another application of rubber cement. While the rubber cement is still tacky I apply a thin sheet of gutta-percha or mending tissue. I I

The sheet of material thus prepared is ready for cuttin into the desired shapes.

Each article cut Ir sired properties. g

It will be understood that it is within the purview of this invention either to increase 0 -or decrease the number of applications of Application filed June 16,

rubber cement and powdered rosin. F or example, under certain conditions it might be more advantageous to make a single application of rubber cement of greater thickness than to make more than one application of relatively less thicknses. Also, the amounts of the various materials used will. vary in accordance with different fabrics used and with different working conditions. The determining factors as to amounts of materials necessary, are for the rubber cement tobe applied thickenough to prevent the molten gutta-percha from'going through the fabric; the amount of rosin or talcum powder used to be su'flicient to insure proper drying of the rubber cement, and the amount of guttapercha to be sufficient to insure the proper adhesion of the article when applied in place. i

I have found that an application of rubber cement which'is about 0.25 mm. thickness when dry and a layer of gutta-percha having a thickness of about 0.70 mm. Wlll ordinarily give satisfactory results The rosin or talcum is dusted on in varying amounts, usuall just enough to cover the rubber cement wit a layer of rosin dust or talcum.

I do not intend to be limited to the specific details of this disclosure except as defined in the appended claims.

Havingthus described my invention, I

claim:

- 1. A laminated fabric comprising a layer of cloth, a layer of rubber cement, a coating of rosin applied thereto, and a layer of guttapercha attached to said layer of rubber cement.

2. A laminated *fabric comprising a-layer of cloth, a first layerTif rubber cement applied thereto, a first coating-of rosin applied to said cement, a second layer of rubber cement applied to said coating, :1 second coating of rosin applied to said second layer of cement.

and a layer of gutta-percha a plied to said last mentioned coating attache to'said layer of rubber cement.

3, A laminated fabric comprising a layer of cloth, a layer of rubber cement, and a layer of gutta-percha.

4. A laminated fabric comprising a layer of cloth, a first layer of rub er cement applied thereto, a first coating of rosin applied to said cement, a second layer of rubber ce-- ment applied to said coating, and a layer of gutta-percha applied to said last mentioned layer.

5. The methodof preparing a laminated fabric which comprises coating a cloth material with rubber cement, applyin arcoating v of powdered rosin to said cement, rying said rubber cement, and applying a layer of guttapercha to said cement coated surface.

Q. The method of preparing a laminated fabric which comprises coating a cloth material with rubber cement, applying a coatin of powdered rosin to said cement, drying sai' rubber cement, applying another coating of rubber cement, drying said last mentioned coating, and applying a layer of gutta-percha to said cement coated surface.

7. The method of preparing a laminated fabric which comprises coating a cloth material. with rubber cement, applying a coating of powdered rosin to said cement, drying said rubber cement, applying a second coating of rubber cement, applying a secon'd coating of powdered rosin, drying said rubber cement, and applying a layer of gutta-percha.
